The paper investigates the evolutionary and expression dynamics of meiotic cohesin genes in teleost fish, showing that whole-genome duplication and regulatory rewiring drive sex-biased expression patterns.

The paper shows that Meioc-Piwil1 complexes regulate rRNA transcription in zebrafish spermatogonial stem cells, preventing Piwil1 from localizing to nucleoli and promoting differentiation.

The paper identifies a dome-shaped microtubule structure in medaka germ cells and clarifies genetic pathways regulating its formation and destabilization during sex determination.

This study identifies a specialized Ran-GTP-driven spindle structure in medaka embryos that ensures accurate chromosome segregation during early cleavage divisions.
